Ο Ολτ (ρουμ. και ουγγ. Olt, γερμ. Alt, τουρκ. Oltu) είναι μεγάλος ποταμός της Ρουμανίας. Οι ονομασίες του στις σύγχρονες γλώσσες προέρχονται όλες από την αρχαία ελληνική ονομασία του, Ἄλυτος, μέσω της λατινικής ονομασίας Aluta ή Alutus. Με μήκος 615 χιλιόμετρα, είναι ο μακρύτερος από όλους τους ποταμούς που ρέουν αποκλειστικά σε ρουμανικό έδαφος, ενώ η λεκάνη απορροής του έχει έκταση 24.050 τετραγωνικά χιλιόμετρα^[1] Η πηγή του βρίσκεται σε υψόμετρο 1.440 μέτρων, στα όρη Χάσμας της ανατολικής οροσειράς των Καρπαθίων, κοντά στην κωμόπολη Μπέλαν και στην πηγή του ποταμού Μούρες. Ο Ολτ διασχίζει 6 διαφορετικούς νομούς της Ρουμανίας: τους Χαργκίτα, Κοβάσνα, Μπρασόβ, Σιμπίου, Βίλτσεα και τον ομώνυμο Νομό Ολτ. Εκτός από τον Νομό Ολτ, και η ιστορική επαρχία της Ολτενίας (γνωστή και ως «Ελάσσων Βλαχία» τον 18ο αιώνα) πήρε το όνομά της από τον ποταμό.

Οι κυριότερες πόλεις από όσες είναι κτισμένες στις όχθες του Ολτ είναι οι Σφίντου Γκεόργκε, Ράμνικου Βάλτσα, Δραγατσάνι και Σλάτινα. Ο Ολτ χύνεται στον Δούναβη κοντά στο Τούρνου Μεγκουρέλε, είναι δηλαδή αριστερός παραπόταμος του Δούναβη.

Φράγματα και λίμνες Επεξεργασία

Για την αποθήκευση πόσιμου νερού και νερού για άρδευση, καθώς και για την παραγωγή υδροηλεκτρικής ενέργειας, 44 φράγματα έχουν ανεγερθεί στη λεκάνη του Ολτ και ισάριθμες τεχνητές λίμνες έχουν δημιουργηθεί. Στον ίδιο τον Ολτ βρίσκονται τα 24 από αυτά, κυρίως για την παραγωγή υδροηλεκτρικής ενέργειας, και άλλα τρία στον παραπόταμό του Λότρου.^[2] Τα 24 φράγματα στον Ολτ, από την πηγή προς την εκβολή του, είναι τα εξής: Βόιλα, Βιστέα, Αρπάς, Σκορέιου, Αβρίγκ, Γκούρα Λοτρουλούι, Τούρνου, Καλιμενέστι, Ντεέστι, Ράμνικου Βάλτσα, Ραουρένι, Γκοβόρα, Μπεμπένι, Ιονέστι, Ζεβιντένι, Δραγατσάνι, Στρεγιέστι, Αρσέστι, Σλάτινα, Ιποτέστι, Δραγανέστι, Φρουνζάρου, Ρουσανέστι και Ιζμπισένι. Η συνολική παραγωγή ενέργειας των 43 υδροηλεκτρικών σταθμών της λεκάνης του Ολτ ήταν το 1996 ίση με 2.980 γιγαβατώρες.^[3]
